The Apocalypse Where Rain Kills Humans

Chapter 2: The Voice of Tlaloc

“This isn’t a storm,” Caio whispered, his voice trembling as he stared at the flickering blue words suspended in the musty air of the basement. “This is a game. And the whole world just lost.”

He waited for a punchline. He waited for Rian to burst through the hatch, laughing about a high-tech prank, or for the screen to glitch out and reveal it was just a hallucination brought on by the toxic fumes. But the text remained rock-steady, glowing with a soft, ethereal light that didn't reflect off the concrete walls the way a normal light should.

“Am I losing it?” Caio asked the empty room. “I’m definitely losing it. Brain damage from the fumes. That’s what this is.”

[USER STABILITY CRITICAL.]

[COGNITIVE DENIAL DETECTED.]

The blue box blinked rapidly, turning a sharp, warning yellow.

[ADAPTING INTERFACE TO LOCAL PARLANCE...]

A new sound filled the room. It wasn’t a beep or a hum. It was a voice—deep, resonant, and sounding like two tectonic plates grinding together. It didn't come from the air; it vibrated inside his skull, rattling his teeth.

“Stop whining, boy. Your brain is perfectly intact. Though, at the rate you’re shaking, your heart might be the first thing to give out.”

Caio jumped, his back hitting a stack of wooden crates with a hollow thud. “Who said that? Where are you?”

“I am the Storm’s witness,” the voice boomed, though it carried a strange, mocking lilt. “You can call me Tlaloc. Or you can call me 'Sir.' Given your current predicament, I’d suggest the latter.”

“Tlaloc?” Caio’s eyes darted around the dark basement. He clutched his burnt arm, the skin still smoldering where the rain had touched him. “Like the Aztec god? Is this some kind of sick cult joke?”

“Cult? No,” Tlaloc replied. The blue screen shifted, displaying a rotating 3D model of the factory. “And Aztec? A quaint label from a dead era. I am the echo of the rain that is currently dissolving your civilization. You should be thanking me. Most of your kind are currently becoming fertilizer for the new world. You, however, found a hole deep enough to matter.”

“Dissolving… my civilization?” Caio’s breath came in ragged hitches. “Rian was on the phone. He said people were screaming. My friend is still in that office building! Can you help him?”

“The one in the glass tower?” The voice sounded almost bored. “By now, the roof has likely turned to slush. The green rain doesn't just burn, Caio. It cleanses. It removes the unnecessary. Your friend is part of the past now. You are the only thing that currently concerns the System.”

“You’re lying,” Caio snapped, his fear momentarily replaced by a surge of white-hot anger. “This is just… it’s a storm! A chemical spill! It’ll stop!”

“Will it?” Tlaloc’s voice dropped to a low, ominous growl. “Look at your arm, boy. Does that look like a chemical spill to you? The essence of the Storm God is in your blood now. You’re changing. Or you’re dying. The choice, as they say, is yours.”

Caio looked down at his forearm. The blackened hole in his hoodie had widened. The skin beneath wasn't just burnt anymore; it was pulsing. Faint, emerald-green veins were branching out from the wound, crawling up toward his elbow like glowing ivy.

“Oh god,” he choked out, his knees buckling. “It’s spreading. Help me. Please.”

“I cannot heal what is meant to be transformed,” Tlaloc said. “But I can give you a chance to survive the process. The basement you have chosen is… adequate. It has the bones of a sanctuary. But a sanctuary needs a Keeper. It needs a soul to anchor it against the deluge.”

“A sanctuary?” Caio looked around at the damp, lightless room. “This is a storage unit for old dye vats! It’s not a sanctuary!”

“It is now,” the voice replied.

[SHELTER LEVEL 1 ESTABLISHED.]

[SYSTEM INTEGRATION: 12%]

“The System has recognized your claim,” Tlaloc continued. “But a claim is just words until it is sealed. You are weak, Caio Prasetyo. You are terrified. You are clutching your arm like a wounded pup while the world ends above your head. Do you want to live?”

“Yes! Of course I want to live!”

“Then stop acting like a victim and start acting like a survivor. The Storm God doesn't give gifts; he offers trades. I have suppressed the pain of your infection for the moment. Consider it a loan.”

Suddenly, the agonizing heat in Caio’s arm vanished. The green veins were still there, glowing faintly in the dark, but the throbbing sensation was replaced by a strange, cool numbness. He could move his fingers again. He stood up, wiping sweat from his forehead with his good hand.

“Okay,” Caio panted. “The pain is gone. What’s the catch? You said there was a trade.”

“The catch,” Tlaloc said, and Caio could almost hear the grin in the entity’s voice, “is that a sanctuary must be fed. You aren't the only one who fled the rain, boy. This basement had residents long before you broke the lock.”

Caio froze. The silence of the basement suddenly felt heavy, pressing against his eardrums. He looked toward the far corner, where the shadows were deepest, tucked behind a mountain of rusted iron vats and rotting crates.

“Residents?” Caio whispered. “You mean like… rats?”

“The rain changes everything it touches, Caio. Even the vermin. One of them caught a stray drop from the vents before you sealed the hatch. It is no longer a rat. It is a hunger.”

A sharp scritch-scratch echoed from the darkness. It was followed by a wet, clicking sound—the sound of something heavy dragging itself over stone.

“Wait, you want me to fight that?” Caio’s voice rose an octave. “I don't have a weapon! I’m an architecture student, not a soldier!”

“You have a pry-bar,” Tlaloc noted. “And you have my Aura. Look at your feet.”

Caio looked down. A faint, circular ripple of blue light was expanding from where he stood, illuminating the floor for about three feet in every direction.

“As long as you are within your Shelter’s heart, you are protected from the worst of the corruption,” the voice explained. “But the creature in the dark is not a part of the Shelter. It is a parasite. If you do not cull it, the System will deem you unworthy, the Aura will fade, and the rain will eventually find its way through the ceiling to finish what it started.”

“You’re insane,” Caio said, reaching out to grab the heavy iron pry-bar he’d used to break in. His hands were shaking so hard the metal clattered against the floor. “I can’t do this.”

“You can, or you can die,” Tlaloc said, his voice booming with a sudden, terrifying authority. “The Trial of the Storm God has begun. There are no spectators in this world anymore, Caio. Only players and corpses. Which one are you?”

Caio gripped the pry-bar. His knuckles were white. He looked at the glowing green veins on his arm, then at the blue circle of light at his feet. The world he knew—the world of exams, coffee shops, and phone calls with Rian—was gone. It had been washed away in a single afternoon of emerald rain.

“I don't even know what I’m looking for,” Caio whispered, his eyes fixed on the shadows.

“You’ll know it when it sees you,” Tlaloc replied.

From the darkness behind the chemical vats, a low, guttural hiss emerged. It sounded like air escaping a punctured tire, but with a wet, meaty undertone. Slowly, two pinpricks of light ignited in the gloom. They weren't blue like the System, or green like the rain.

They were a sick, sulfurous yellow.

The eyes were wide, unblinking, and positioned much further apart than any rat’s should be. As the creature shifted, the light from Caio’s feet caught the glint of something wet and jagged—rows of teeth that had grown too large for the creature’s mouth, stretching its jaw into a permanent, skeletal grin.

“Holy…” Caio’s breath hitched.

The creature stepped into the faint periphery of the light. It was the size of a large dog, but its body was twisted, its fur sloughing off in wet clumps to reveal raw, pulsating muscle. It moved with a twitchy, unnatural grace, its claws clicking rhythmically against the concrete.

“It’s waiting,” Tlaloc whispered in his ear. “It smells the Storm in your blood. It thinks you’re a meal. Prove it wrong.”

The creature let out a high-pitched, warbling shriek and crouched low, its yellow eyes locked onto Caio’s throat. Caio raised the pry-bar, his heart hammering against his ribs like a trapped bird.

“Come on then,” Caio growled, the terror in his chest turning into a desperate, jagged sort of courage. “Come and get it.”

The beast lunged.
